Internal thread high-pressure low-temperature needle valve is a precision valve designed specifically for extreme working conditions, suitable for low-temperature medium systems such as liquefied natural gas, liquid oxygen, and liquid nitrogen. It adopts internal thread connection method, which is convenient for installation and sealing; The valve body material is mostly stainless steel or low-temperature carbon steel, ensuring stable operation within the range of -196 ℃ to room temperature; The needle type valve core structure can achieve precise flow regulation and reliable cutoff, with high pressure resistance and excellent sealing performance. It is widely used in fields such as chemical, energy, and air separation equipment.
Welding high-pressure needle valves for power plants are designed specifically for thermal power generation, nuclear power, and supercritical units
Used for high temperature, high pressure or extremely dangerous medium systems to eliminate the risk of leakage. The 90 ° angle flow channel design is easy to install and drain, and the precision conical needle valve core is equipped with a hard alloy seal to achieve precise adjustment of micro flow and zero leakage shut-off.
The integrated welded double needle valve is primarily used in gas dispensing devices, serving as an instrument root valve or process valve.
